Twinlab - Magnesium Caps High Potency 400 mg. - 100 Capsules

A Potent Mineral for Good Health
Magnesium is an essential mineral for calcium and potassium assimilation and helps support proper nerve-muscle impulses, enzyme reactions, bone health, and carbohydrate metabolism. Also a cofactor for more than 600 biochemical reactions in your body, Magnesium assists with processes including efficient fatty-acid synthesis, protein synthesis, calcium-balance regulation, and also helps fight constipation, reduce the number and intensity of migraine headaches, stress, and anxiety, and improve your heart health. Each 1-capsule daily dose of Twinlab Magnesium Caps delivers you 420, representing 100% of your daily recommended value.

    Staggering Magnesium Deficiencies
    As you age, your body becomes less efficient at absorbing essential vitamins and minerals, even if you pride yourself on eating a healthy diet. Magnesium is one of those minerals, and experts believe that as many as 80% of Americans don’t get enough of it from diet alone – in foods like seaweed, basil, flaxseed, cumin seed, parsley, leeks, kale, and almond butter. What’s more, very little of this mineral resides in your blood, so there isn’t a perfect blood test that puts it high on your doctor’s list of concerns.

    Primary Benefits
    Magnesium is involved in more than 600 reactions in your body, some of the primary ones including help in converting the food you eat into energy; creating new proteins from amino acids; helping create and repair DNA and RNA; playing a role in contraction and relaxation of your muscles; and helping regulate your neurotransmitters, which send messages throughout your brain and nervous system.

    But There’s More!
    Proper Magnesium intake also has been shown to help improve exercise performance, during which you may need 10%-20% more magnesium than when you’re at rest, so supplementing with Twinlab Magnesium can help you perform at your best. In fact, studies have shown that supplementing dietary Magnesium intake can boost exercise performance in athletes, the elderly, and people with chronic diseases. Other benefits shown through research include Magnesium’s ability to help you fight depression; improve blood-sugar levels if you have type 2 diabetes; help lower your blood pressure; help you avoid chronic inflammation, which is one of the drivers of disease, obesity and aging; help improve PMS symptoms; and possibly help prevent migraine headaches.

    Are You at Risk for Deficiency?
    People with higher risks of developing Magnesium deficiency include people who eat a consistently low-magnesium diet; people with gastrointestinal disorders, those who drink excessive alcohol, are pregnant or lactating, have type 2 diabetes, are elderly, or take antibiotics or diuretics. If you do not believe you are getting enough Magnesium in your diet for optimal health, a supplement like Twinlab Magnesium Caps can play an important role in helping you maintain bone mineralization, protein formation, heart health, reduced stress levels, and more. Purchase yours on today and take a giant step forward on your road to optimal health!

    Twinlab High Potency Magnesium Caps contain 400 mg of magnesium. Magnesium is an essential mineral for calcium and potassium assimilation, and helps support proper nerve muscle impulses, enzyme reactions, formation of bone and carbohydrate metabolism. Magnesium Caps provide a natural, magnesium supplement with 400 mg, or 100% of the daily value, of magnesium.

    Twinlab Magnesium Caps:

    • Natural
    • Highest Potency

    Magnesium is an essential mineral to the human body. It is needed for bone, protein, and fatty acid formation, making new cells, activating B vitamins, relaxing muscles, clotting blood, and forming adenosine triphosphate (ATP; the energy the body runs on). The secretion and action of insulin also require magnesium.

    Where is it found?
    Nuts and grains are good sources of magnesium. Beans, dark green vegetables, fish, and meat also contain significant amounts.
